Virtual Partitions (vPars) enable you to transform virtually any HP 9000 system into multiple "virtual computers," each running their own instance of HP-UX and associated applications. Now, one of the world's leading HP-UX experts presents a comprehensive guide to vPars that covers everything you need to succeed with this breakthrough technology. Poniatowski introduces vPars' key concepts, explaining how vPars enables multiple virtual computers to be fully isolated from each other on the same HP 9000 server -- running multiple instances of HP-UX 11i, different patch levels, and different applications. He then covers not only every vPars command, as well as the system administration techniques you need to take full advantage of it. He walks setting up and configuring vPars; then covers every aspect of managing HP-UX, including working with device files; using System Administration Manager (SAM) and Service Control Manager (SCM); adding peripherals, users, and groups; utilizing Ignite-UX; performing backups; and more. For every HP-UX administrator, and for sophisticated HP-UX users seeking to benefit from vPars technology.
